I say its never too late to make a good first impression.
1) read the 'intros' made by others and try to make one that is even better.
post it in the Newcomers' section and PUT your location in BOTH your intro and as suggested by Alaskan in your PROFILE.= I just looked and it is NOT there. And it needs to also to be in the Title of the intro=-=like 'hello--new guy here from Texas'.
A second and better intro is OK for this use.. not as good as just adding info to your 'old intro'--
BUt you can fix this.
1) add location into your profile and when you repair your 'intro; the location is best in the title.
2) Give us , please a little more--first name is good. occupation--goals with lasers- other hobbies etc.
3) while you are editing PLEASE combine your 'doubles' into just one post (the ones back to back are double posts and it is frowned upon here). There are a few exceptions but your triples do not fall into that area.
